FP-790T User Manual 6-3
Replace the backlight according to the procedure below. (The following explanation
assumes that the FP has already been removed from the panel)
6-3 Changing the Backlight
• Be sure the FP's power cord has been disconnected prior to
changing the backlight. When the FP's power cord is connected
and the FP is ON, high voltage runs through the wires in the
backlight area. Do not touch them!
• When the FP's power cord has just been disconnected, the back-
light area is still very hot! Be sure to wear gloves to prevent be-
ing burned.
• The backlight is very fragile. Do not touch the glass tube directly
or try to remove its power cord. If the glass tube breaks you may
be injured.
Warning
• During replacement, be sure to protect the front surface of the FP’s
display so that it is not scratched or damaged.
• The FP has both an upper and a lower backlight bulb. Be sure to
replace both at the same time.
• Since CFL is used for the backlights, they should be disposed of in
a manner appropriate to your local government’s laws or
regulations.
